Title: Semiconductor device
Inventor: SAKAGAMI MASAHIKO
IPC: H01L27/04
Filed: 1989-05-24
Abstract: PURPOSE:To prevent a circuit block from malfunctioning due to the fluctuation of a power source or a ground potential by a method wherein a circuit constituted on a semiconductor substrate is divided into, at least, two circuit blocks, and the pads and the circuits of the power source or the ground are made independent by blocks. CONSTITUTION:An output transistor circuit 12 and another inner circuit 13 are constituted on a semiconductor substrate 11 in such a manner that they are considered to be divided into two blocks from the standpoint of a power source supply. The operating current of the circuit 12 flows through a power potential Vcc lead 22, a Vcc pad 14, the circuit 12, and a ground potential Vss outer lead 25; therefore, the potentials Vcc and Vss, supplied to the circuit 13, are prevented from fluctuating. The operating current of the circuits 13, when the circuit 12 is in operation, flows only through the lead 22, a Vcc pad 15, a Vss pad 17, and the lead 25, so that the potentials Vcc and Vss applied to the circuit 12 are prevented from varying and consequently the output signal of the circuit 12 is hardly distorted.

Abstract: PURPOSE:To enhance checking speed and reliability of checking, by comparing a read pattern of a printed serial number with a predicted pattern corresponding to the number. CONSTITUTION:Accurate typefaces for each digit constituting serial numbers 2 to be printed on a sheet S are previously stored in a central processing unit 5 as fundamental data. Further, an initial number is inputted to the unit 5. When the first number being printed is brought to the position of a line sensor 6 by drawing-out rollers 3, a read pattern of the number is inputted to the unit 5. In the unit 7, an accurate predicted pattern of a digit train corresponding to the number at that time is formed based on the fundamental data. The read pattern and the predicted pattern are compared with each other, and when the difference between the two patterns is within a predetermined allowable range, printing is continued. The acceptability of the sequentially printed numbers is discriminated, and when the difference between the read pattern and the predicted pattern of the printed number is outside the allowable range, a printing machine 1 is stopped, and the defect in printing is corrected.

Title: Output voltage controller for solar battery
Inventor: YABE YASUSHI
IPC: H01L31/04
Filed: 1982-07-27
Abstract: PURPOSE:To perform continuous voltage control by using a phototransistor, solar battery, etc., as a photodetecting element for control in an electronic calculator which drives a liquid-crystal device. CONSTITUTION:The phototransistor PT is used as the photodetecting element and its base is connected to solar batteries SB1-SBn in parallel together with a resistance R connected to the collector as a light input. When illuminance increases, the output voltage VA of the solar batteries SV rises. At this time, the collector-emitter impedance of the phototransistor PT decreases gradually to the contrary and the base voltage VB of a transistor TR drops gradually. Consequently, the collector-emitter resistance of the TR increases to obtain a greater voltage drop. Thus, the output voltage of the solar batteries is controlled to a constant voltage by utilizing the characteristics of the transistor PT for control.

IPC: G11B7/09
Filed: 1989-05-25
Abstract: PURPOSE:To remove offset to be caused in focus and tracking error signals with simple configuration by detecting the rotating quantity of a far field image to be caused by the turn of the main body of an optical pickup based on the detected output of a second optical detector. CONSTITUTION:One of the focus and tracking error signals, at least, is detected by a first optical detector 10 and the quantity of the rotation to be caused by turning a main body 100 of the optical pickup, in the far field image is detected based on the detecting output of a second optical detector 11. Based on this quantity of the rotation, the offset to be generated in the error signal is removed by an offset removing means. In such a case, since a track 102 of an objective lens 9 draws a circular arc when the main body 100 of the optical pickup 100 is tunned, the far field image of the track on a disk 17 is rotated on a four-dividing PD 10 and a rotational angle detecting PD 11 of the optical pickup. Thus, the offset to be generated in the focus and tracking error signals can be removed by the simple configuration.

Abstract: PURPOSE:To sufficiently control an energy of ions in the plasma with a DC voltage of acceleration power supply and leads the sufficient amount of ions of adequate energy to the target by inserting insulated transformer between a matching circuit and an electrode. CONSTITUTION:An insulated transformer 11 where the primary side and the secondary side are insulated is inserted between an output end of a matching circuit 8 and a terminal of a high frequency coil 7. For example, a chamber 1 to be exhausted is exhausted, the Ar gas is supplied to said chamber, and the chamber 1 to be exhausted is filled with the plasma ambient by applying a high frequency voltage from a high frequency power supply 9. Where an evaporating material in a crucible 3 is vaporized by the electron beam impact under this condition, the vaporized particles are ionized and ion energy is activated by a DC voltage of acceleration power supply 10 and the ions are adhered to the target 2. Since a high frequency voltage to be applied to the high frequency coil 7 from the insulated transformer 11 is a floating voltage, a potential for the earth of plasma formed around the high frequency coil 7 is positive, the ion in the plasma is energized by a negative DC voltage applied to the target 2, and such ions are running to the target 2.

Abstract: PURPOSE:To omit a RAM for correction or a shift register for correction by preparing the memory areas in response to the positions of plural image sensors and correcting the address value of the image data to be compensated when the image data are written into or read out of those memory areas. CONSTITUTION:A correction circuit 64 corrects the address of the image data produced by an image sensor and to be compensated, and the picture memories 3 are prepared in response to plural image sensors respectively.
